CosyVerif

Software Environment for the Formal Specification and Verification of Dynamic Systems

What is CosyVerif ?

CosyVerif is a software environment whose goal is the formal specification and verification of dynamic systems.

This environment consists of two software tools: Coloane, the graphical interface; and Alligator, an integration framework web service. CosyVerif is enlarged with the existing verification tools developed in our laboratories (founding members or partners).

Extensible

Support different formalisms and offer the possibility to create and integrate new tools

Why CosyVerif ?

The development of CosyVerif has been decided and it is supported by three partners of the Parisian verification group, MeFoSyLoMa, which is composed of seven teams. The founding members of CosyVerif are LIP6, LIPN and LSV.

First, these members aim at sharing their tools, comparing and supporting industrial case studies and finally making them long-lasting. Second, they also want to promote the practice of formal verification in industry and thus they intend to ease the task of integration of new formalisms and tools.

Managing CosyVerif

CosyVerif is managed by a steering committee consisting of researchers and engineers. It decides strategic orientations as well as technical choices.

Current Tools

Two formalisms are supported: automata and Petri nets, both with extensions.

Most of the tools are related to Petri nets. Some of them perform structural analyses like invariant computations while other tools perform behavioural analyses: symbolic reachability graph building, unfolding, stochastic simulations, etc. Finally some of them transform high-level nets into low-level ones.
